Abstract
A method and treatment for testing efficiency and effectiveness of a near infrared photoimmunotherapy treatment includes injecting an antibody photosensitizer conjugate (APC) into a patient, applying radiation to the patient, thereby causing the APC to release a ligand, which is excreted in the patient's urine, detecting the presence of the ligand with liquid chromatography-mass spectrometry, measuring and quantifying an amount of the ligand present in the patient's urine based on analytical results of the liquid chromatography-mass spectrometry, and determining the effectiveness of the near infrared photo-immunotherapy treatment based on the measured quantified amount of the ligand present in the patient's urine so as to determine an amount of APC remaining in the patient.
